HENRY J. ENGLAND, OF FALLS CHURCH, VIRGINIA.

LIFTING-JACK.

SPECIFICATION forming part of Letters Patent No. 299,529, dated June 3, 1884.

Application filed May 2, 1884.

To all whom it may concern Be it known that I, HENRY J. ENGLAND, .a citizen of the United States, residing at Falls Church, in the county of Fairfax and State of Virginia, have invented certain new and useful Improvements in Lifting-Jacks, of which the following is a specification, reference. being had therein to the accompanying drawings.

My invention relates to certain new and useful improvements in lifting-jacks; and it consists of a central support fulcrumed between a pair of continuous hoop-shaped lever-arms, or lever-arms formed from a single piece.

The object of my invention is to provide a neat, serviceable, and cheap lifting-jack that will be light and strong, that can be easily used with one hand of the operator, that will easily lift the axle of any vehicle and hold the same in place securely while the wheel is removed for lubricating the axle, or for any other purpose. I attain these objects by means of the peculiar construction and arrangement of the various parts of my device, which will be more fully pointed out and described in the specification and claims, reference being had to the drawings accompanying this application and forming part of the same, in which Figure 1 is a perspective View of my invention with the parts closed. Fig. 2 is a sectional elevation of the same, showing it in position for use. Figs. 3 and 4 are modifications showing the device closed.

Similar letters refer to similar parts throughout the drawings.

Referring to the drawings, A represents a pair of continuous arms that are formed of a single piece of wood or metal bent at or near the center to form a loop or handle, A, similar to a basket-handle, the outer ends of said piece being thickened and brought together evenly to form a support, B, and their extreme ends are provided with one or more metallic points, 0, said point or points being formed to prevent the lower end of support B from slipping when in use.

near their extremities to receive a bolt, E, by which they are joined and held firmly in place, said bolt being formed screw-threaded at one end and provided with a binding-nut or put through the perforations plain and riveted down.

The ends. B are perforated (No model.)

or said bolt may be made plain and riveted A short distance from loop or handle A a perforation is formed through the arms A to receive a bolt, H, which may be formed screw-threaded with a binding-nut or riveted down. A central support or lifting-bar, F, is formed of proper thickness, either angular or round, and of suitable length when placed in position to lift the axle of a vehicle or other object the required distance. The extreme inner end of said lifting-bar F is formed rounded or of suitable shape to fit closely against the outer face of concavity b, and partially or entirely rest thereon when lifting any object. A short distance from said inner end a cross-perforation, c, is formed to receive bolt G, 011 which said lifting-bar F is pivoted and by which it is loosely held in place, said bolt G serving to aid in supporting said lifting-bar.

when in use, or may entirely support said bar F. The outer end of lifting-bar F is formed flat or oval, and provided with a corrugated rubber or metallic pad, d, to prevent slipping or bruising the object raised. A short distance inward from said end a bracket, 6, is secured on the outer face of said lifting-bar, to catch under the front axle of a vehicle or other object of less height from the ground than that lifted by the end of said bar. Bracket e is also provided with a corrugated rubber pad, f, to prevent moving or slipping.

Fig. 1 shows my device with the arms made of a single piece of material, wood, or metal, the outer ends bent inward to join and forma solid base, the center to form a grip piece or handle, the lifting-bar put in place, and the device closed.

The device in position to begin lifting on front axle, A is shown in sectional View in Fig. 2. A flexible connecting-strap, I, is sesaid strap formed of suitable length to hold the litting-bar F at the requisite angle when in use.

The modification or different form of constructing my device is shown in Figs. Band 4., in which a single piece of wood or metal, A, is out lengthwise to within a short distance of one end, which is left solid to form a bearing, B, which is provided with pointed projections 0. Between the cuts thus made a center-piece is taken out which forms the liftingbar l3, and by means of this construction a very cheap and durable lifting-jack is made. The lifting-bar is otherwise formed, as hereinbei'ore described, and the sides of the frame or body A are perforated to receive bolts G and H, and the outer ends of arms A. are provided with a straight handpieee, J, secured by a bolt, K,or a curved metal piece, L, secured by screw-bolts g, as shown in Fig. 4, the operation of the device being the same in each case. The square block A shown on bracket 0 represents a section of the forward axle of a vehicle.

01. a single piece of wood or metal, the center cut out to form a lifting-bar,wl1ich is pivoted between the cut sides, the free ends of said piece being held in place by a straight handpiece and bolt, substantially as shown.

3. Alifting-jack, consisting of abody formed of a single piece of wood or metal, the center out out to form a lifting-bar, which is pivoted between the cut sides, the free ends of said piece being held in place by a curved hand- 4 piece secured by scrcw bolts, substantially as shown.

at. In a lifting-jack, the bent body A, the thickened bearin g part B, havingpoints G, the tie-bolt E, the pivot-bolt G, the holding-bolt H, and the roundedhandle-part A, in combina tion with the liftingbar F, having bracket 0, provided with corrugated plate f, and the flexible conneeting-stra I, all arranged and operated substantially as shown and specified. 5

In a liltingjack, the body A, having end bearing, B and straight sides A the pivotpin G, the binding-bolt H, and the curved handle L, secured by screw-bolts g, in COlllbl nation with the lifting-bar, F, pivotedbetwecn sides A, and having bracket 0 and the flexiblo strap C, connecting-bolt H, and bar F, all arranged and operated substantially as shown and specified.

In testimony whereof I affix my signature in presence of two witnesses.
